Downloading Eye Tracking Data from Iris

A.k.a. exporting eyetracking data

Setting Up

First, connect to the VPN and the BLab-Share (Fas-Phyc-PEB-Lab)on Iris.

Downloading the Data

  • Open DataViewer from the Start Menu.

  • Click the icon in the upper left hand corner that looks like this:

  • A new window will ask you for the location of the files you want to import.

    • Click the button next to the filepath to select the location of your experiment's files.

    • You want the folder called 'results', which should be in your experiment's Desktop shortcut.

    • For example: Desktop/YM/YMjuly10/results

  • Import. This may take a while depending on how many subjects you have.

  • After the dataset has finished importing, go to File > Save As. Name your folder [Experiment][date_of_download].res (i.e. YM8_29_17.res)

  • Set utf-8 as the encoding for the output files. Under Insperctor -> Preferences, make sure that "Use UTF8 Encoding" is checked.

  • Select Analysis > Reports >Fixation Report.

    • Click the first Available Variable in the list, then scroll to the bottom of the list.

    • Hold down SHIFT on the keyboard and select the last Variable in the list, so that the entire group will be highlighted.

    • Move all the variables over to the box on the right using the right arrow button between the boxes.

  • You should be prompted to save again. Save as "[Experiment]_fixrep_[first subj_num]_to_[last subj_num]" and click Save. Putting the subject numbers in the export will stop you from having to re-export the same participants more than once, and will also help you keep track of what's in the fixrep.

  • Select Analysis > Reports > Message Report.

    • Select all of the variables and move to the box on the right.

    • Save as "[Experiment]_mesrep_[first subj_num]_to_[last subj_num]" and click Save.

To get this data off of Iris, you'll want to save it on the Fas-Phyc-PEB-Lab/experimental_projects/[your_study]/eyetracking_data server. If this is the first time you're exporting a fixation/message report for this study, create a folder within your study subfolder called eyetracking_data, then put your data in a subfolder called [Experiment][date_of_download]. In there should be the fixrep and mesrep files.

Make sure when you're dating things that you include the year also! You will be surprised at how many "feb_21"s happen while you're still collecting data!

You might have created a folder called Output when you were exporting your data. That's okay! If so, you can just pull that whole folder into the subfolder you created.
